The battery grip was delivered quickly. At the beginning everything was fine. After about a year to use the following fault pattern found. The menu behaved always surprising. Menu items are automatically selected, there lies no longer be controlled or jumped at any location. The photo preview could occasionally not appear. First, the camera in suspicion. Latest firmware recorded. Was it but unfortunately not. I became aware of an observed error on the battery grip by doing research for another camera. So tested and actually. Without battery grip the camera is working properly. The errors occur with battery grip. Perhaps this recession helps explain similar behavior in other cameras.
